    Description / Table of Contents: Preparation, Structure, and Thermolysis of DiiminePure diimine can be easily obtained by the thermolysis of alkalimetal tosylhydrazides Tos(M)N2H2 (Tos = p-CH3C6H4SO2; M = Li, Na, K) in high vacuum. Diimine is deposited as brilliant yellow solid on a finger cooled at -196°C. On the basis of infra-red spectroscopic investigations it has been found to be trans-configurated. The diimine thermolysis starts at -180°C and leads mainly to nitrogen and hydrazine (disproportionation of diimine), but also to some extend to nitrogen and hydrogen (decomposition of diimine), ammonium azide (dimerization of diimine), as well as nitrogen and ammonia (cleavage of diimine).
    Notes: Die Thermolyse von Alkalimetall-tosylhydraziden Tos(M)N2H2 (Tos = p-CH3C6H4SO2; M = Li, Na, K) im Hochvakuum ist ein einfaches Verfahren zur Darstellung von reinem Diimin. Das nach infrarotspektroskopischen Untersuchungen trans-konfigurierte Diimin läßt sich als leuchtend gelber Feststoff an einem -196°C-Kühlfinger niederschlagen. Als Produkte der bie -180°C einsetzenden Thermolyse erhält man aus Diimin hauptsächlich Stickstoff und Hydrazin (Diimin-Disproportionierung) sowie untergeordnet Stickstoff und Wasserstoff (Diimin-Zerfall), Ammoniumazid (Diimin-Dimerisierung), Stickstoff und Ammoniak (Diimin-Spaltung).
